I have a 77 CJ5 that's been refurbished over the years and I'm doing it again.
This past weekend, I took out the seats and all the old carpet and inspected everything.
The metal seat bottoms that support the foam cushion are rusted out and the foam cushions are all chewed up and nasty. I'll be getting new lowback seats of junkyard seats. The carpet, of course, let moisture rust around one of the seat/frame mounting holes and also one of the seat belt mounting holes..
I should take some pics so you all could see, but the bottom of the floor pan just behind the gear shifter where it meets the step up to what I'd call the 'bed' area is rusted out also....this is where the seat belt mount is rusted out. There may be a second seat belt mount rusted too, but one of them pulled completely out (Driver's seat right floor mount).
I want to get new seats, but before I do I need to reinforce the floor in the area of the one seat mount (passenger seat mount front right mount) and the seat belt mount(s).
I'm not too worried about the seat belt mounts as I feel like I can find a suitable mounting place to change it to, but the seat HAS to mount in the same place, right? What would be the best way to bolster this rusted seat mount?
I'm not going to tub swap now, because this is basically a farm truck at this point, and I'm wanting to just 'fix' this rusted out spot.
Will it be okay to have some bracing underneath welded on and just make a mounting plate?
What have some of you done for rusty floor mounts?
I'm not familiar with the suppliers due to the lack of a need for it here in my area, but there are companies that make patch panels. I'm sure if you searched you may come up with something. If not, you will probably have to find an intact jeep tub to take measurements from and fab up your own.
You can get pre-formed steel panels to repair Jeep CJ tubs, but I have heard complaints that they're not as thick as the original 16 gauge steel. Plus, they are large and cover big areas of the tub like the whole floor area under the driver's feet. When I repaired my tub I bought a 4x8' sheet of 16 gauge steel and used that as needed to repair about 11 different rusty areas.
Post some good quality photos of the rusty areas and we can get you more specific information.

Depends on how big the rusted area is. My seat mounts were cracked on the DS near the door so I hammered it back as well as I could, welded it and then put a strip of 1/8" steel over it but mine were not rusted out.
